BED-LOCK FOR lNK-TABLE-DISTRIBUTION PRESSES.

Specification of Letters Patent.

Patented May 15, 1906.

Application filed September 6, 1904. Serial No. 223,353.

To all whom, it may concern.-

Be it known that I, JOHN C. BERMINGHAM, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Bed-Locks for Ink-Table-Distribution Presses, of which the following is a specification.

My invention relates to improvements in bed-locks for inletable-distribution presses;

and my object is to provide simple means for quickly and reliably locking the chase containing the type in any desired position upon the type-bed of a printing-press.

The invention consists of a longitudinal bar for engaging one side of the chase, extensionbars for holding the transverse bar against the chase, keys for reliably locking the extensionbars .in place, and a pair of side lock-clamps adjustably arranged on the transverse bar and adapted to engage two opposite sides of the chase to prevent the latter from crawling or shifting on the type-bed.

In the accompanying drawings, which illustrate the invention, Figure 1 represents a plan view of a type-bed and ink-distribution table provided with myimprovements. Fig. 2 is a longitudinal section of the same, taken 011 line II II of Fig. 1. Fig. 3 is a transverse section of the ink-distribution table, taken on line III III of Fig. 1. Fig. 4 is a detail transverse section taken on line IV IV of Fig. 1. Fig. 5 is a detail perspective view of one of the side lock-clamps. Fig. 6 is a detail perspective view of one of the keys employed for locking the extension-bars against accidental movement.

In said drawings, 1 designates the ink-distribution table. 2 is the type-bed, provided with the customary flanges 3, and.4 designates a pair of clamps secured to the forward end of the type-bed. All of these elements are in general use and form no part of the invention.

5 designates a pair of pockets in the under side of the ink-distribution table communieating at their forward ends with apertures 6, through which a pair of extension-bars 7, slidably arranged in the pockets, project, said extension-bars being provided at their upper front corners with transverse flanges 8, adapted to contact with either the front surface 9 of the ink-distribution table or with keys 10, and thereby limit the inward movements of said extension-bars.

Each extension-bar is provided at its longitudinal sides with alternately-arranged rectangular teeth 11-that is to say, the teeth on one side of the bar are arranged opposite the recesses 12 on the opposite side of the bar in order to provide a finer adjustment with the key, which latter has a centrally-disposed recess 13 for the reception of the extensionbar, and depending lugs 14 at its opposite ends adapted to alternately enter the recesses 12, and thus reliably lock the extension-bar from backward movement.

Keys 10 are held downwardly against accidental disengagement from the extensionbars by the upper walls 15 of recesses 16, which are longer than the keys in order that the latter may be shifted longitudinally to engage the recesses on either side of the eX- tension-bars. (See Fig. 4.)

17 designates a transverse bar, which is slightly shorter than the width of the space between flanges 3 and provided at one end 1 with a set-screw 18, which, when adjusted outwardly, presses against one of flanges 3 and forces the opposite end of the bar tightly against the other flange, and thus holds the bar against accidental movement. Said setserew is provided with an apertured head 19 for the reception of a pin or a nail, whereby it is turned, an opening 20 being provided in the bar to permit the latter movement.

21 designates a pair of side lock-clamps, each of which comprise a bar 22, provided at one end with a recess 23 for fitting over the transverse bar, a set-screw 24 for securing bar 22 at any point of its adjustment on transverse bar 17, and an adjusting-screw 25 at its opposite end for engaging one side of the chase 26.

In practice the chase is looked at any desired point upon the type-bed by placing,

transverse bar 17 against its rear side. (See Fig. 1.) Said bar is then looked from accidental movement by the proper adjustment of set-screw 18. Said bar is then positively locked from backward movement, in which direction the chase exerts its greatest pressure thereon, by the extensionbars, which are drawn out into contact therewith and reliably locked by the keys 10. The chase is then looked from forward movement by clamps 4 and one ormore filling-strips 2 6 pressed tightly against the front side of the case by said clamps.

The chase is held from lateral movement by the locking-bars 21, which are secured upon transverse bar 17 by set screws 24, after which the inner ends of screws 25 are adjusted against the opposite sides of the chase.

When a chase is used that is large enough to snugly fit the type-bed so that it may be reliably secured thereon by clamps 4 and a filling-strip, keys 10, transverse bars 17, and the side lock-clamps are removed and the extension-bars are pushed back in pockets 5 until flanges 8 contact with the vertical surfaces of recesses 16.

While I have shown but two extension-bars in the drawings, three or more will be used on presses having large type-beds to prevent the middle portion of bar 17 from springing backwardly under pressure from the chase. It may also be desirable at times to employ but one of the side lock-clamps, in which case one side of the chase will be held in contact with one of flanges 3 by a side lock-clamp abutting against the opposite side of said chase.

While I have shown the preferred form of the invention, I of course reserve the right to make such changes as properly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In an apparatus of the character described, in combination, a type-bed, an inkdistribution table communicating therewith and provided with a pocket, the upper surface of said table being arranged in a higher plane than the upper surface of the type-bed, an extension-bar adjustably arranged in the pocket and adapted to be slid outwardly upon the upper surface of the type-bed, and means for locking said extension-bar from backward movement.
